I use pychecker when I have finished a chunk of work that is supposed to 
be syntactically correct, but before I try any unit testing. Think of it 
as an optional step that takes the place of running the compiler in 
statically-typed language development. I use pytchecker again before I 
release anything, just to be sure.

Suppression lists work for me.

 From http://pychecker.sourceforge.net/

You can also define suppressions in your code by doing:

         __pychecker__ = 'no-namedargs maxreturns=0 unusednames=foo,bar'

*** end quote ***

pychecker complains a lot when used on code that is poorly written and 
includes bad practices such as using builtin function names as local 
variable names. I consider pychecker's complaints in these cases to be a 
*feature*.
